Getting data from different entity sets from back-end at once
I have created a custom Fiori app. My requirement is when I press a Add button, a form opens in which the user needs to fill data in the drop-downs. Each drop-down will get the data from different entity sets from ODATA. I am using filter method to fetch data.Since the control is going to back-end multiple times(for each drop down list), the time consumed is more (approx 2 mins). Is there any way by which I can get the data in one go and make the operation of loading Add page faster?
I think you can improve the speed of the app by using the concept of Batch Requests.
The idea is to group several odata requests, in just one.
